Manganese cobalt nickelate films (MnxCoyNi3-x-y)O4 (MCN) are successfully prepared by chemical deposition method
at a crystallization temperature of 600°C, which is greatly reduced from the traditional sintered temperature of ~1050 -
1200°C. From the XRD and AFM, we find the grain size of the MCN films increases from 20 to 60 nm with the
annealing temperature increase from 600°C to 900°C.
